IMMT1/2, PRM

Mechanical Motion
- Smooth pico motion and its default position
- Gaps between magnets and coils

Spectrum

Mirror conditions(??)
- Clean around the center?

Beam Path from IMC to PRM (Yokozawa, and Akutsu)

Activities:

IMC to STM1

Beam clearance: OK

STM1/2

Beam position on IMMT1
Trans beam of IMMT1
- No change to ISS path?
- ISS beam/CWP reflection beam extracting (??)
- the beam paths are clear?
- The beams hit around the center of windows?
- The reflected beams on the windows are dumped?

IMMT1-IMMT2

Beam clearance: no problem
Beam position on IMMT2: shifted from the center.

IMMT2-PRM

Main beam/misaligned beam clearances: no problem against the beam dumper
The misaligned beam position: hits on the dumper(?) and the temp enhancement was detected.

Around PRM

Beam position on PRM
IR beam in the midsize baffles(HR/AR side)

Main Beam Dumper

Thermometer works: https://klog.icrr.u-tokyo.ac.jp/osl/?r=29340
Visual Inspection: after the IR recovery.
Beam Clearance: OK with the main IR beam

Beam dump(T.Akutsu)

some shiny remnant: https://klog.icrr.u-tokyo.ac.jp/osl/?r=29343, https://klog.icrr.u-tokyo.ac.jp/osl/?r=29342
Beam dumps were additionally added?
- In basic, No. Relocation was done?

PRM Cleaning

PRM

Oplev Check for IMMT1. (Yokozawa-kun)

Activities:

Beam Power

Beam Path Clearance

IMMT1

QPD centering

Calibration

Spectrum Health

Oplev beam's stray light influence

almost no light? as before.

Oplev table covering

we will do this after closing.

ISS path

Check the path by Miyakawa-kun

Vacuum system (Kimura/Uchiyama and their selected persons)

Close GV btw PRM and PR3 and stad bolt nut adjustment btw PRM and PR3

Clean inside as much as possible including the bellows duct with TMP

Check the flange seal surface condition where were opened.

KF400 flange with a Copperplate -> change with a curved flange.

Decide where the elastomer/Metal gasket will be used.

Logistic to reinstall the bellows duct with TMP.
